Answer:
Our maximum is 19 when x=3 and y=7 and our minimum is -21 when x=3 and y = -3
Step-by-step explanation:
First, we can graph these inequalities out. As you can see in the picture, the three vertices where the inequalities all connect form a triangle. We can check each of these vertices to find our minimum and maximum.
First, we have (3,7). 4y-3x = 4(7)-3(3)=28-9=19
Next, for (3, -3), we have 4y-3x = 4(-3)-3(3) = -12-9=-21
Finally, for (0.5, 2), we have 4y-3x=4(2)-3(0.5)=8-1.5 = 6.5
Our maximum is 19 when x=3 and y=7 and our minimum is -21 when x=3 and y = -3
Answer:
false, it's the opposite so its doesn't have the same amount, negative or positive.
Answer: F. Parameter, because the data set of all 2000 students in a high school is a population.
Step-by-step explanation:
Parameters is a variable or measure that is calculated from the entire population of data while a statistic is done from a sample of the data.
The question notes that the poll was done on <u>all 2,000</u> students in a high school. This means that the poll is a Parameter because it was done on the entire population of the high school.
Answer:
(x²+5)(x-9)
Step-by-step explanation:
Assuming that you are asking to factor by grouping:
x³ - 9x² + 5x – 45
You can group:
x²(x-9) + 5(x-9)
and then combine the x² and 5:
(x²+5)(x-9)
Start at (0, 135) and work your way down 15 and over one each time. Your next point would be (1, 120)
